Gc not tow a trailer during the break-in kriod of your vehicle.
Keep an eye on your coolant tempera-
fere gauge. If coolant temperature warn- rc light comes on pull off the road to a sa's place to allow engine to cool down.
Maximum trailer weight
A vailer for your vehicle is limited to a
typi-

ca class I trailer. The maximum gross
Bier weight and the tongue load must not
eoeed the specifications listed in the
[fechnical Information/Data section of this
ranual.

Do not exceed the gross vehicle weight
•rhich is the weight of the driver, passen­ ger, luggage, trailer hitch and tongue
weight of the loaded trailer. Trailer hitch
Use a weight-carrying hitch conforming to
the gross trailer weight. The hitch must be suitable for your vehicle and trailer and
securely bolted to the body. Always check
with the trailer hitch manufacturer to make
sure that you are using the correct hitch. Do not use a bumper hitch.
The hitch must be installed in a way not to interfere with the impact-absorbing
bumper system. No modifications should
be made to the vehicle exhaust and brake
systems. From time to time check that all hitch mounting bolts remain securely fas­

tened.

If not towing a trailer for a long period of

time,
remove the trailer hitch. This pre­
vents the hitch from causing damage should your vehicle be struck from behind.
When removing the trailer hitch, seal all bolt holes to prevent water and exhaust
fumes from entering the vehicle.
Trailer brakes If your trailer is equipped with a braking

system,
check to be sure that it conforms
to all regulations.
The trailer brake system must not be di­ rectly connected to the vehicle's brake sys­

tem.
Tire pressure
When towing a trailer, inflate the tires of
your vehicle to the cold tire pressure listed on the label on the left front door jamb. In­
flate trailer tires to trailer and tire manufac­
turer's specifications.
Safety chains
Always use safety chains between your car and trailer.
Trailer lights
Trailer lights must meet all regulations. Do not connect the trailer light system directly
to the light system of your vehicle. Be sure
to check with your Volkswagen dealer for
correct wiring, switches and relays.
Before you tow a trailer
Correct and even load distribution. All ob­
jects inside the trailer should be held securely in place to guard against shifting, be it forward, backward or sideways.
Never allow a passenger in a moving
trailer.

VEHICLE OPERATION

For
best roadability adjust your load to the
maximum allowed tongue load. To be sure

measure
tongue load of loaded trailer on
bathroom
scales.

Check
that
both sides of your trailer can be

seen
from the driver's seat. If necessary in­
stall extended rear-view mirrors.

Check
proper working of vehicle and
trailer lights.

Check
cold
tire
pressure of both vehicle

and
trailer.

Be
sure trailer safety chains are properly

connected
from trailer to the hitch on the

vehicle.
Leave enough slack in the chains
to permit turning corners.

Trailer
towing
tips
Your
vehicle handles differently when tow­ ing a trailer because of the additional
weight. Safety, performance and economy
will greatly depend on how carefully you
load
your trailer and operate your "rig."
Before
you actually tow your trailer, prac­
tice turning, stopping and reversing in an
area
away from
traffic
until
you learn the
feel of your vehicle and trailer
unit.

Reversing
is
difficult
and requires practice.

Steering
while reversing is generally oppo­
site of
that
when backing your vehicle with­
out a trailer.

Observe
speed limits. In some areas

speeds
for vehicles towing trailers are lower than for regular vehicles.
Maintain a greater distance between your

vehicle
and the one in
front.
You will need more room to stop.

When
passing remember
that
you cannot
accelerate
as fast as you normally would

because
of the added load. Make sure you
have
enough room to
pass.
After passing
allow plenty of room for your trailer before

changing
lanes again.

Avoid
jerky starts or sudden acceleration.
Slow
down in crosswinds and on rougi"

roads.
Be especially carefull when
pas­

sing
other vehicles and trucks.

When
parking always block the wheels o: both vehicle and trailer. Do not park
with
a
trailer on a slope. If it cannot be avoided dc
so
only after the following:
• Apply brakes.
• Have someone place wheel blocks
under both vehicle and trailer wheels.
• With wheel blocks in place slowly re­

lease
brakes
until
wheel blocks absorb the

load.

• Apply parking brake.
•
Place
transmission in
"P"
for automatic
or in
first
or reverse gear for manual trans­
mission.

VEHICLE OPERATION

I'iving
off-road on Steep Inclines
I Sidehills
Before reviewing how to drive up steep
• s and along sidehills, make note of an -oortant point. If you don't make it to the

co.
or your vehicle is about to slide or roll
= :eways,
turn
off the engine, put it
into

I
'3t
gear, put on the parking brake and get

W
on the uphill side and walk down. An
:^nce
of prevention is
worth
a pound of i.re.
Steep
Inclines
When preparing to climb a steep incline,
first
find out whether you can make it. If
necessary,
walk the course. Be sure there

is
enough clearance on all sides of the ve­
hicle to avoid damage. If you have the
slightest doubt don't try it! It is always a
good idea to make a
trial
run to get the feel
of the surface and how much
effort
is
needed.
Go straight uphill. When the tires
begin to
spin,
apply a
little
extra gas and let
them dig in slightly. Step on the brakes
while you shift
into
reverse and drive straight back down. That's
right
- in re­

verse
gear, clutch out and driving.
Abso­
lutely not in neutral and
trying
to let your­
self down on the brakes. To avoid sideroll remember never
turn
your vehicle
side­

ways on a hill or steep incline.
On
your attempt, give yourself a running
start. Accelerate to the hill and then,
just

as
you approach the top,
ease
off the gas
to slow down.
When driving down, keep the vehicle heading straight downhill in low gear and
under control. If it begins to slide, don't lock up the brakes. You can't steer a
skid­

ding wheel. Touch the gas instead to
straighten your car out.

VEHICLE OPERATION
Sidehills
Do
not
attempt
to go across the side of a
hill as this is extremely hazardous. If it is
absolutely necessary to drive on a hill
which is not very steep it should always be
done
with
extreme caution. Whenever
possible,
avoid doing it! And too, when
you're getting out of your vehicle on a
sidehill,
be sure to always exit on the uphill

side.
Surfaces
on sidehills are deceptive. What
may look like solid ground may actually
make your vehicle slide since most of the
weight is going to be on the downhill

wheels.
When your vehicle starts to slide, instantly
turn
downhill. Take care not to
lock the wheels which may cause the vehi­

cle
to slide out of control and cause per­
sonal
injury.
Sand
When driving on
sand,
be sure to stay on top of it. You can do this by driving
with
enough speed to maintain momentum.
When crossing short patches of
sand,
study the situation
first
and then proceed

with
cautious and steady speed and keep up the momentum. Avoid long stretches of
dry, loose
sand.
If it is absolutely neces­

sary
to drive on dry, loose
sand,
it may be
necessary
to partially deflate the tires to in­

crease
traction. To avoid getting stuck, maintain a steady but slow
speed.

WARNING

Tires
must
be
reinflated
when
back
on
hard
ground. Just a
short
distance
of

driving
on
hard
ground
or on
pavement

with
underinflated
tires
can cause sub­
stantial
damages
to
your
tires,
loss of

vehicle
control
and
personal
injury.

VEHICLE CARE
BRAKE FLUID 3 ATT
108 Brake fluid reservoir
The brake fluid reservoir is located under the instrument cluster in the dashboard
panel.

To gain access to the reservoir, grasp the two recesses provided on back of the frame cover and pull up.
When replacing the cover, insert the front edge first, then press the cover down
firmly. Make sure it is correctly seated.
Checking fluid level
The correct fluid level is important for the proper functioning of the brake system.
The fluid level in the brake fluid reservoir should always be between the MAX and MIN markings. Your brake fluid level is automatically monitored by the brake
warning light (see page 43).
The fluid level may drop slightly after some time due to the automatic adjustment of
the brake pads. This is no cause for alarm.
If the brake fluid level falls considerably
below the mark
"MIN",
the brake warning
light will come on. Do not continue to oper­
ate the vehicle. The complete brake sys­
tem should be thoroughly checked by your
Volkswagen dealer and the cause cor­
rected.

WARNING • Brake fluid is poisonous. Brake fluid
is also harmful to the paint of your
vehicle.
When adding or replacing brake fluid, make certain to avoid spilling. Brake
fluid will damage fabric, paint, plastics and metal. Cover the areas sorround-ing the reservoir before removing the
filler cap.
• If brake fluid must be added to the
reservoir, use only new and unused
DOT 4 brake fluid that meets SAE
specification J 1703 and conforms to Federal Motor Vehicle Safety Standard

116.
• Do not use any other brake fluid, or
brake fluid that has absorbed moisture
from the open air, or brake fluid that is
dirty. It may cause premature wear or unreliable braking action.
• Do not add or mix DOT 5 silicone
type brake fluid with the brake fluid in your vehicle as severe component cor­rosion may result. Such corrosion
could lead to brake system failure.
Changing brake fluid Brake fluid absorbs moisture from the at­
mosphere. If the watercontent in the brake
fluid is too high, corrosion in the brake sys­
tem may result after a period of time. The boiling point of the brake fluid will also de­
crease considerably. If the brakes are under constant and extreme use, a vapc
lock may result impairing the effectiveness
of the brakes and the vehicle safety. -e s
Dn seat arc
WARNING
The brake fluid must be replaced every 2 years. Your Volkswagen dealer will perform this service for you.
Always heed WARNINGS on page 97.
